Intra-annual vertical profiles of physical and chemical parameters at the Ghiffa pelagic station during 2011 (45°57′N, 3°46′W: 370 m depth). Temperature in °C (a), oxygen concentrations in mg L−1 (b), and chlorophyll concentrations in μg L−1 (c) were measured every two weeks at intervals of 0.5 m. Concentrations of reactive phosphorous in μg L−1 (d), ammonium in μg L−1 (e), and nitrate in μg L−1 (f) were measured at 0, 5, 10, 20, 30, 50, 10, 150, 200, 250, 300, and 350 m depth.
